This is listed on IMDB as a 1937 movie, but it was really released in 1938 (discounting a New York only premier). Nothing much different here from the other Bulldog Drummond movies I've watched. My favorite parts still involve Drummond's valet, Tenny. He cracks me up.

Briefly, there is a new dangerous explosive called 'Haxonite' which has been purloined by the bad guys. There is a chase from London towards Paris on the "boat train" or "train ferry". Drummond always seems to be working his way slowly toward marriage.
